Description

Technical Field

[0001] This utility model relates to the technical field of reinforcement structures for foundation pits, specifically a novel reinforcement structure for foundation pits that saves materials. Background Technology

[0002] An excavation pit is a pit dug at the foundation design location according to the base elevation and foundation plane dimensions. It is an underground cavity excavated during building construction and is usually used for constructing underground structures or temporarily excavating earthwork. After the excavation of the excavation pit is completed, reinforcement mechanisms need to be installed around the pit to reinforce it and prevent the pit from collapsing and affecting the construction of the superstructure.

[0003] However, the existing reinforcement structures around the foundation pit are mostly installed and positioned by horizontal supports. The horizontal support method requires more components and the installation process is more complicated, time-consuming and labor-intensive, which affects the construction progress of the foundation pit. Secondly, the existing foundation pit is prone to water seepage after excavation, which affects the construction at the bottom of the foundation pit. Utility Model Content

[0004] To address the problem that installing and positioning the reinforcement structure around the foundation pit using horizontal supports is complex and affects the construction progress, this utility model aims to provide a new type of reinforcement structure for foundation pits that saves materials.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a novel reinforcement structure for foundation pits that saves materials, comprising a foundation pit body, wherein a uniformly arranged support pile is installed at one end of the bottom surface of the foundation pit body, a construction ring beam is fixedly installed on the top surface of the support pile, a top plate is fixedly installed on one side of the construction ring beam, a uniformly distributed rotating seat is fixedly installed on one side of the top plate, and a uniformly distributed anchor pile is installed on the bottom surface of the foundation pit body located on the side of the support pile;

[0006] An anchor rod is fixedly installed on the top surface of the anchor pile. A positioning plate is fitted on the surface of the anchor rod and fits against the top surface of the anchor pile. A positioning buckle is inserted into one side of the rotating seat. A rotating component is rotatably installed inside the rotating seat and on the surface of the positioning buckle. A nut is threaded on one side of the surface of the positioning buckle. A steel support is fixedly installed on one side of the rotating component. A positioning seat is fixedly installed at the end of the steel support away from the rotating component. The positioning seat is slidably inserted into the surface of the anchor rod. A nut is threaded on the surface of the anchor rod.

[0007] Preferably, a water-stop curtain is installed inside one side of the foundation pit body, and the water-stop curtain cooperates with the foundation pit body.

[0008] Preferably, the support pile is thicker at the top and thinner at the bottom. Both the support pile and the anchor pile are pre-cast concrete. The rotating part has a positioning hole in the middle. The positioning buckle is slidably inserted into the positioning hole. The rotating part rotates on the surface of the positioning buckle through the positioning hole. The positioning seat has an insertion hole in the middle. The insertion hole cooperates with the anchor rod.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. In this utility model, the support piles are evenly installed and fixed on the four sides of the foundation pit body. The construction ring beam is installed and positioned on the support piles by multiple sets of steel supports in conjunction with the top plate. Later, the connection between the construction ring beam and the support piles is completed by pouring concrete in the construction ring beam, thus completing the reinforcement work on the four sides of the foundation pit body. This is convenient, quick, time-saving and labor-saving. It does not require horizontal support to complete the installation and positioning of the reinforcement structure around the foundation pit body, thus improving the construction progress of the foundation pit body.

[0011] 2. In this utility model, the foundation pit body is waterproofed by installing water-stop curtains on all four sides of the foundation pit body to prevent water seepage from affecting the construction inside the foundation pit body. The thinner part of the bottom of the support pile is inserted into the bottom surface of the foundation pit body to fix the support pile. This not only reinforces the foundation pit body around the foundation pit body, but also saves materials and reduces costs. Attached Figure Description

The positioning of construction ring beam 3 is completed by multiple sets of steel supports 5 in cooperation with top plate 31. Later, the connection between construction ring beam 3 and support pile 2 is completed by pouring concrete in construction ring beam 3, and the reinforcement work on four sides of foundation pit body 1 is completed. It is convenient, quick and easy, saves time and effort, and does not require horizontal support to complete the installation and positioning of reinforcement structure around foundation pit body 1, thus improving the construction progress of foundation pit body 1.

[0021] A water-stop curtain 6 is installed on one side of the foundation pit body 1. The water-stop curtain 6 works in conjunction with the foundation pit body 1 to waterproof the foundation pit body 1 by installing water-stop curtains 6 on all four sides of the foundation pit body 1, preventing water seepage from affecting the construction inside the foundation pit body 1. The support piles 2 are thicker at the top and thinner at the bottom. Both the support piles 2 and the anchor piles 4 are pre-cast concrete.
